Given an input that looks like this:
[
{
id: 11,
valueId: 22,
valueDescription: 'Some value',
referenceId: 33,
referenceDescription: 'Some reference',
groupId: 44,
groupDescription: 'Some group'
},
{
id: 55,
valueId: 66,
valueDescription: 'Another value',
referenceId: 77,
referenceDescription: 'Another reference',
groupId: 88,
groupDescription: 'Another group'
}
]
And a desired output of:
{
entities: {
types: {
"11": { id: 11, valueId: 22, referenceId: 33, groupId: 44 },
"55": { id: 55, valueId: 66, referenceId: 77, groupId: 88 },
},
values: {
"22": { id: 22, description: "Some value" },
"66": { id: 66, description: "Another value" },
},
references: {
"33": { id: 33, description: "Some reference" },
"77": { id: 77, description: "Another reference" },
},
groups: {
"44": { id: 44, description: "Some group" },
"88": { id: 88, description: "Another group" },
}
},
result: [ 11, 55 ]
}
I'm not sure how I'd define Schemas for my 4 entity types that would pull multiple fields off of the flattened root object and also rename them. I see there's the assignEntity argument I can pass which I think I would use for the renaming part, but I'm not sure how I would define a Schema to indicate that one flat object becomes four entities.

On the vuetify treeview component the #input event is triggered when the selected array is initialised, I don't want this behaviour, I need the input event to be triggered only when the user manually selects/deselects an item
<v-treeview
selectable
selected-color="red"
:value="selected"
:items="items"
#input="input"
></v-treeview>

}
}

Here is a codepen with the problem - https://codepen.io/amaieras/pen/yLPLyvZ?editors=1011
See that the alert is shown even if I don't trigger any selection, can I avoid this from happening?
{
{
id: 125,
apartments: [
{
floor: 28,
},
{
floor: 29,
}
],
},
{
id: 126,
apartments: [
{
floor: 25,
},
{
floor: 29,
}
],
},
....
}
It is sample collection data.
Now I want to filter this collection by floor attribute. For example, I want to get only floor == 29
I want to get all the data that including floor == 29.
How can I filter it?
My goal is to normalize this object:
{
talks: [
{
id: 1755,
speakers: [
{
id: 1487,
name: 'John Doe',
},
],
related_talks: [{
id: 14,
speakers: [{
id: 125,
name: 'Jane Doe',
}],
event: {
id: 181,
name: 'First Annual',
},
}],
event: {
id: 180,
name: 'July Party',
},
},
],
};
into this result:
{
entities: {
events: {
181: {
id: 181,
name: 'First Annual'
},
180: {
id: 180,
name: 'July Party'
}
},
speakers: {
125: {
id: 125,
name: 'Jane Doe'
},
1487: {
id: 1487,
name: 'John Doe'
}
},
talks: {
1755: {
id: 1755,
event: 181,
speakers: [ 1487 ],
related_talks: [ 14 ],
},
14: {
id: 14,
speakers: [ 125 ],
event: 180,
}
},
},
result: {
talks: [ 1755, 14 ],
},
}
If you'll notice, the items in related_talks are treated the same as a talk.
My schemas follow the examples and are set up like this:
const speaker = new schema.Entity('speakers');
const event = new schema.Entity('events');
export const talk = new schema.Entity('talks', {
speakers: [speaker],
event,
});
talk.define({ related_talks: [talk] });
No matter what I try, I can't get the items in related_talks to be added to the result.talks array. It is, however, in the entities object.
What is my schema configuration missing in order to accommodate this?
Unfortunately, if this is your requirement, Normalizr is not for you. Alternatively, if you're looking for a list of "talks" by ID, you can use Object.keys(data.entities.talks)
Docs:
[{
id: 111,
weight: 1
},{
id: 222,
},{
id: 333,
weight: -1
}]
I want to order the docs by weight if weight not exists treat its weight as 0
How can I do that ?
You can use function as mentioned here with default:
r.table(TABLE_NAME).orderBy(r.asc(function(doc) {
return doc("weight").default(0)
}));
